I’m ready to move an industrial-grade controller board from 50K units to 500K Units production and need a China-based ODM and PCBA house that can step in, refine the current design, and run the line at scale. The board already works in the field, yet a few component swaps and layout tweaks are required for smoother manufacturability and lower cost. Once those engineering changes are locked, I want to transition straight into volume builds without handing the project off to yet another shop, so I’m looking for a single partner that covers everything from engineering updates through surface-mount, wave solder, functional test, and final pack-out. What matters most to me is seamless communication, transparency on component sourcing, and proven experience with industrial-equipment standards—temperature, vibration, and long lifecycle parts are key. If you regularly work with Altium or KiCad files, can generate a thorough DFM/DFA report, and have in-house testing (ICT or flying-probe) you’re already ahead. Deliverables (project milestones) • Updated schematics, BOM, and Gerber set reflecting my requested modifications • DFM/DFA feedback with recommended cost-down or risk-reduction actions • Pilot build (≈50 pcs) plus full test results • Final quotation and ramp-up plan for mass production, including lead-times and QC checkpoints I’m happy to provide the current CAD files, firmware, and performance specs under NDA. Let’s discuss how you can take this board from revised design to thousands of units in the field, all under one roof in China.

As an experienced Electrical Engineer, I bring a wealth of knowledge in circuit design, electronics, and PCB layout, all of which align perfectly with your project goals. Not only have I successfully completed and delivered projects at scale, but I've also worked extensively with industrial-grade standards similar to what your project requires - temperature, vibration, and long lifecycle parts. Additionally, my proficiency in using Altium Designer and KiCad will ensure efficient communication and accurate DFM/DFA feedback for a cost-effective solution. I've also amassed significant experience in sourcing components from China, ensuring transparent communication channels throughout the process. Given the opportunity, I can take your 50K unit production to 500K units while making the design smoother to manufacture with lower costs without compromising on quality. Most importantly, I've been through every phase of product development from initiating ideas to delivering market-ready products. From system architecture to firmware development, PCB designing to AI/ML integration and IoT connectivity, I can offer end-to-end service that you're looking for. The same diligence extends to post-production matters such as testing (ICT or flying probe), ensuring thorough documentation and packaging for final product delivery. With me on your side, you'll have a single partner dedicated to achieving revolutionary results.

Hi, I am interested in supporting your controller board transition from prototype to high-volume production. My background includes PCB design, embedded systems, DFM/DFA optimization, electromechanical product development, and manufacturing support, with experience preparing products for reliable mass production. I understand that your board is already field-proven and requires engineering refinement to improve manufacturability, reduce cost, and ensure long-term supply stability before scaling to 500,000 units. I can support the project by: Reviewing and updating the existing Altium or KiCad design Optimizing the schematic, PCB layout, and BOM for cost, reliability, and manufacturability Performing comprehensive DFM/DFA reviews and recommending component substitutions where appropriate Supporting functional test strategy, ICT/flying-probe requirements, and production validation Preparing complete manufacturing documentation, including Gerbers, assembly drawings, pick-and-place files, and BOMs Coordinating with experienced China-based PCBA and ODM manufacturers to support pilot production and volume ramp-up Best regards,

Most PCB designers deliver Gerber files and move on. I design boards that are ready to manufacture the first time. I'm Ting, a PCB designer and firmware developer with 14+ years of experience. Before becoming an independent engineer, I worked at READA PCB Technology in Shenzhen as both a PCB designer and later a production manager. I reviewed customer designs for manufacturability every day, so I understand the issues that cause delays, assembly problems, and unnecessary manufacturing costs. My expertise includes: PCB layout from 2 to 16 layers High-speed routing and controlled-impedance design Mixed-signal, power, and EMI-conscious layouts Altium Designer, KiCad, and Eagle (licensed) You'll receive a complete production package, including: PCB layout and schematic updates (if required) Bill of Materials (BoM) Gerber and ODB++ files Pick-and-place files Assembly drawings DRC report 3D STEP model If you need working hardware instead of just design files, I can also coordinate PCB fabrication, PCBA, component sourcing, functional testing, and worldwide shipping through READA and my trusted manufacturing network in Shenzhen. I'm happy to sign an NDA before discussing your project and can start immediately. I look forward to hearing about your design requirements. Best regards, Ting
